Liver Disease in Older Dogs

Liver disease in older dogs

It feels like liver disease in older dogs is an illness not talked about as often as kidney disease, or diabetes, am I right?

We know it exists, we know dogs are afflicted with it, but I rarely hear it mentioned, except when my vet told me there was a problem with Red’s liver.

It is most commonly found in older dogs, although dogs of any age can be affected due to genetics or external/environmental factors.

What is the function of the liver?

I have heard the liver referred to as the “workhorse” of the body.  It…

  • Produces bile that aids in digestion
  • Metabolises fats, carbs and proteins
  • Helps blood clotting
  • Breaks down drugs
  • Removes toxins from the body
  • Stores vitamins and minerals

Symptoms of liver disease in dogs

Many of the symptoms of liver disease are the same as for other illnesses, so my best advice is to see your vet whenever you notice in behaviour changes, no matter how slight they may be. 

Have you noticed any of the following?

  • Peeing more
  • Weakness/lethargy
  • Symptoms of liver disease in dogsDrinking more
  • Depression
  • Blood in/ dark coloured pee
  • Vomiting
  • Diarrhea
  • Weight loss
  • Confusion
  • Apathy
  • Loss of appetite
  • Jaundice
  • Seizures
  • Enlarged abdomen caused by fluid build-up

Dogs with advanced liver disease often suffer neurological and behavioural changes. This is due to the high levels of toxins in the body that would normally have been removed by a healthy liver.

Signs you may see include:

  • Seizures
  • Wandering
  • Disorientation
  • Aggression
  • Restlessness
  • Pacing
  • Drooling

Skin disorders in dogs with advanced liver disease may also occur.

Causes

Possible causes of liver diseaseThere are several possible causes including:

  • Being a common illness in old dogs
  • Infection
  • Medication
  • Trauma
  • Other diseases
  • Genetics
  • Toxins (plants, herbs, pesticides…)
  • Long term use of painkillers
  • Fatty foods

Diagnosing liver disease

Your vet will ask about your dog’s diet, medication he’s taking, any chance he got into something he shouldn’t and changes you may have noticed. Blood tests and urine tests are pretty standard “starting point” diagnostic tools in my vet’s office, and they will probably be in yours as well. The next step will depend on test results.   

Treatment

As with every condition, the treatment will depend on the diagnosis. How quickly was it caught? How advanced is it?

A change in diet, milk thistle (a supplement known to be good for the liver – in humans as well!), SAMe (naturally produced by the liver and available as a supplement), medications, IV fluids to prevent dehydration, medications to control vomiting and even surgery are all possibles.

Prevention

Many causes are not preventable, but here are things you can do for your old dog’s overall health and wellbeing…

  • Senior dogs should have twice yearly check ups, unless your vet is monitoring a condition and more frequent trips are needed. Routine blood tests, for example, can detect elevated liver enzymes so prompt action can be taken.
  • Take your dog to the vet as soon as you notice any changes in behaviour, no matter how minor you think they are. Early diagnosis means early treatment, and can prevent liver damage.
  • Avoid feeding fatty foods
  • Provide him with a healthy, nutritionally balanced diet
  • Appropriate exercise
  • Access to fresh, clean drinking water
  • Know the poisonous plants or insects in your area
  • Keep dangerous substances out of your dog’s reach

Liver disease in older dogs – conclusion

Even if a large percentage of a liver is diseased, it has a remarkable way of still working. Depending on the severity of the illness, dogs can live comfortably for years after a diagnosis. As I keep saying, get your dog to the vet when you notice any change in behaviour. Older dogs can go downhill very quickly, so time is of the essence.

I do hope you have found this post on liver disease in older dogs informative.
